Struct ConnectOptions 

pub struct ConnectOptions { /* private fields */ }

Options for an outbound connection.

use net_io::{ConnectOptions, TcpConnection};
use std::time::Duration;
let options = ConnectOptions::new().timeout(Duration::from_secs(3));
let conn = TcpConnection::connect_host("example.com", 443, options)?;
println!("connected to {}", conn.peer_addr());

Implementations

impl ConnectOptions

pub fn new() -> ConnectOptions

Timeout 10 s, TCP_NODELAY on, no local bind.

pub fn timeout(self, total: Duration) -> ConnectOptions

The total time for all attempts.

pub fn local_addr(self, addr: SocketAddr) -> ConnectOptions

Binds to this address before connecting.

pub fn tcp_options(self, options: TcpOptions) -> ConnectOptions

Options applied before the connect.

pub fn limits(self, limits: Limits) -> ConnectOptions

Limits for the connection.

pub fn happy_eyeballs(self, on: bool) -> ConnectOptions

Happy Eyeballs (RFC 8305, simplified because std resolution returns both families at once): attempts overlap instead of waiting for each other, IPv6 first and the families interleaved, and the first established connection wins. The total timeout still bounds everything; the others are reset.

pub fn attempt_delay(self, d: Duration) -> ConnectOptions

How long an attempt runs alone before the next one starts (250 ms; held to 100 ms through 2 s). An attempt that fails starts the next at once.

Trait Implementations

impl Clone for ConnectOptions

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConnectOptions

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConnectOptions

fn default() -> ConnectOptions

Returns the “default value” for a type.
